We have an amazing Creator who designed our bones to be both hard and flexible.
(Apparently the kids realize that the surface behind the bones was reflective. I did not notice this until… um… 2 minutes ago.)
This is a great experiment that you can do to understand how God made our bones.
I always thought calcium made strong bones because it made them hard. This is true, but our hard bones would be brittle if they didn’t have a flexible component called collagen. It is the combination of the hard and the flexible that makes our bones strong. Our bodies are designed in amazing ways. This experiment will help you see the hard (but brittle), and flexible characteristics of our bones.
I am going to summarize what we did in this post, but you can click here for the details of the experiment from Answers in Genesis.
You will need 2 bones. The experiment called for chicken bones, but we used turkey bones, which are larger, so the experiment took a lot longer to work.
Place one bone in a container of vinegar, and set the other bone aside. After 2 weeks (or 4 weeks in our case), the bone will be flexible. This bone still looked normal, but could be bent and twisted. It felt strange bending the bone because we knew it was a real bone.
After the first bone became flexible, we put the other bone on the grill. I am not sure what the optimal time is for this step. I forgot to set a timer, but I think it was about 10 minutes with the grill on high. This bone was still hard, but was so brittle that I accidentally broke it in half before I showed the kids. The kids had fun breaking the bone into little bits.
The experiment takes time as the bone soaks, but it actually takes very little time where you have to do something.
Next time you have chicken bones, try this experiment and see the wonderful design that God put in our bones.
